Carlos and maria drove a total of 258 miles in 5 hours. carlos drove the first part of the trip and averaged 53 miles per hour. maria drove the remainder of the trip and averaged 51 miles per hour. for approximately how many hours did maria drive? round your answer to the nearest tenth if necessary. 1.5 hours 1.8 hours 2.5 hours 3.5 hours

Maria drove for 3.5 hours.

Step-by-step explanation:

Carlos and Maria drove a total of 258 miles in 5 hours.

We can write the equation as :

or  

where c is the time taken by Carlos and m is the time taken by Maria.

Carlos drove the first part of the trip and averaged 53 miles per hour. Maria drove the remainder of the trip and averaged 51 miles per hour.

Now substituting the value of c here, we get

So, m = 3.5

Hence, Maria drove for 3.5 hours.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
